how old are you? did you live through the megaupload era? for a few years it was ubiquitous and def a cashcow machine
Not that that justifies anything, people should be free to keep as much physical cash as they want.
Don't see what's wrong to preserve your property outside of the modern banking system if you are against the US.
But no matter how big/small he is, I don't approve of other countries extraditing their citizens to the US for things they did while physically outside the US. Especially when the US wouldn't do the same when it comes to its citizens.
